Ocean is an integral part of our environment, upon which many depend for survival, and it is a basic element of the Earth’s climate. It is also an important site of transit for both goods and people. Therefore, understanding both the state of the ocean and the ways in which it might change is crucial.
Pierre Bahurel and his team from Mercator Ocean in France have, together with ESEOO in Spain, developed a global eddy-permitting model which allows a realistic representation of the main ocean currents.
They have also been able to study for the first time the coupling between sea ice and a global eddy-permitting ocean. Understanding this coupling is essential to efforts to realistically simulate circulation in the high latitude ocean, which has consequences for large-scale ocean circulation and deep water formation.
Achievements have also been made at a more regional level, especially in the North Atlantic area. The research group has managed to represent correctly the Gulf Stream pathway and in particular the separation of the current from the coast at Cap Haterras to become a zonal jet in the Atlantic.
A supercomputing infrastructure is essential for oceanographic modelling in order to generate ever more realistic simulations of the ocean’s behavior. Computation capacities provided by DEISA (Distributed European Infrastructure for Supercomputing Appications) have enabled research group to carry out interannual simulations, which are crucial for testing the validity of the models, for setting up systems of operational oceanic forecasting, and for deepening the understanding of the ocean more generally.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
